JOSEF MARIAN, OF VIENNA, AUSTRIA BOTTLE CAPPING MACHINE .Application iled March 19, 1931, Serial No. 523,810, and in Austria March 18, V1930.

rIhis invention relates to bottle machines. v

Among the important objects of the invention are to provide an improved general construction of machine for this purpose; to provide a capping machine wherein a die is used for forcing the cap down on the bottle and cheeks or jaws are used to crimp the cap into a groove in the bottle neck, the mechacapping nism used being of improved and novel construction; to provide a machine of this class having a novel arrangement of neck engaging clamps for holding the bottle during the capping operation proper;'and to provide operating means arranged by a single movement to successively actuate the neck clamps, the die andthe-cap crimping cheeks in the order named.

One form of the device for the carrying out of the process according to the inven-f tion, and three forms of cap for use in conc junction therewith, are shown, by way of eX- ample, in the accompanying drawings, in which Figs. 1 and 2 show the said device before the beginning of the closing movement, in vertical section and plan elevation respectively,

Figs. 3 to 8 represent'details of the device in elevation, p

Figs. 9 and 10 show the device at the termination of thel closing movement, invertical section and side elevation respectively,

Figs. 11 and 12 show a detail of the device, in idejelevation and plan view respectively, an f Figs. 13 to 15 show three forms of the closing cap, in section. Y c y f Referring to Fig. 1 the neck 1 of the bottle is provided with two external grooves 2, 3, and with a shoulder 4 on the inner surface of its orifice. This shoulder is adapted to receiveVv and support the packing 5 of the cap 6, when the latter is placed over the mouth of the bottle. c

The cramping tool comprises a casing 7 the lid 8.of rwhichY has acentral aperture 9 toreceive the neck ofthe bottle. The upper constricted portion of this casing is provided internally with steep-pitch threading 10 with the bottle.

which a screw-disc 11 (Figs. 11 and 12), serving as a pressing die, is adapted to engage. Thisrdisc is provided with concentric slots 12 to receive pins 13 attached to the under surface ofl a plate 14. The screw-disc l1 is pressed against the plate 14by a spring 15 inserted between a collar on the plate14 and the Vhead of a bolt 16 screwed into the disc 11.

l/Vith the plate 14 there is connected a cap 17 Vwhich embraces the upper vportion of the casingr7, and also an arm 18 which, together with an arm 19 attached to the casing 7.

forms the handles for the operation of the del vice, to be moved in the manner of the handles of a pair of pliers. In the lower portion of the casing 7 there are located in superposition vfour rings 20-23 21 with tangential slots 26, and the ring 22 with angular slots 27 each formed of a tangential and a ,concentric portion. Between the rings 2O and 21 there are arranged four ring segments 28 (see Fig. 4) which serve for the clamping of the device on to the neck of IEach of these segmentsl is provided on bothl sides with pins 29 which engage in the slots' 24, 26.0f the discs 20, 21. Be-

tween the rings 22 and 23 there are arranged eight segments (see Fig. 7) adapted to act as crampingl cheeks, in two layers .of four each, of which the lower are denoted by 30 and the upper by 31. Each segment is provided on both sides with pins 32 which engage in the slots 27, 25 in the rings 22, 23. Y

The ring 21 is provided with an extension 33 projecting from the casing 7, to which eX- tension there is attached an angle-piece 34 which is connected with the arm 18 by means of a tensile spring 35. VThe ring 22 is likewise provided with an extension 36 to which a frame 37 is attached through which the arm 18 projects. The arms 18 and 19 are-pressed apart by means of a spring 38. The Ymode of operation of the device is asV follows v After the placing of a closing cap 6 With its packing upon the mouth of the bottle to be sealed, and after the-fitting of the device over the same, the arms 18 and 19 are pressed together. It is possible to effect this with one hand, since an angle of movement of about 26 is sufiicient for the present purpose. The work of cramping on lthe cap is effected, during the pressing together of the arms 18 and 19, inthe following three stages :-YK

1. The arm 18 moves with it the anglepiece 34, through the intermediary of the spring 85, so that the ring 21 is turned in the casing. rFhe segments 28 arefthereby com-' pelled to move radially inwards so as to engage in thegroove 2 in the neck ofthe' bottle, .and thus to clamp the device in position on the bottle. The length Vof the yslots v12, inthe screw-disc V11 areso proportioned that the pins18 travel idly in these slotsduringt-his first stage. Y

' 2.V On the further movement of the arm 18 the. pins- 13 carry the screw-disc'forward with them compelling l Wards in the screw-threadinglO, so that the closing cap is pressed down, and its packing compressed to a thickness of about 4 mm. rlfhe plate 14`participates the downward movenientgof the screw-disc under the influence of the spring 15 v until the same is checked, e. g. until the rim of the cap 17 meets the shouldered-out surface of the casing 7. Qn the further rotation of the plate the pins 13 must withdraw from theslots 12.

3. The lever 18 now comes in contact-with the'frame 87, and effects the vrotation ofthe disc 22, whereby the cheeks 30, 31 aremoved inwards, so that the wall of the closing cap is pressed into the groove 3 in the bottle-neck. The device has now attained theposition in which it is shown in Figs. 9 and 10. On the releasing of the arms 18, 19 these same are pressed apart bythe spring 38, and the screwdisc 11y is Ylifted by the spring 15.v

' 'ljhe cap 17 is provided, as shown inl Fig. 10, with slots 39 in which pins 40v attached to the wsid@ @fthe ,Casing engage Ther@ efe-thus provided retaining means `for the cap 1 7 A.and the plate 14 connected therewith, so that these parts cannot be lifted `by the reaction to the pressure exertedon the screw-'disc 11 during the second stage of the lcramping process. 1t is also possible to employ, in placeofthe screw-disc 11, a merely axially guided pressing die the downward movement of which iseected-by the oblique portion of the slots 1t will be clear from the above description that the device. can be 'constructed as a hand tool, so that the present invention enables even the smallest businesses, which 4are not in a position-to install expensive sealing plant,

to'eifectithe tight sealing of their products in e manner Whihtis beth Simple .and-'i11- expensive. The device can, however., alsobe the same to'move downknown capsule Stoppers the new cap provides the further advantage of great saving of n provided with an annular inwardly projecting fold 41 by means of which the packing 5 .isretained inposition in the cap before use.

l In the form of cap shown in Fig. 14 the v.side wall is returned inwardly and its edge 42 isreturned again an ,axial direction so as to form a ring-shaped rib for holding the packing 5 in position. l i

The packing can also be' attached to the inside of the cap in any other desi-red or adhesive.

cap Gis provided with an annular depression 44, being curved upwards. The disc 11 has a projecture 45 on Vits undersurface, acting Referring to Fig. 15, the head 43of the suitable manner, for example by means of an uponthe curved portion of the head and pressing the edge 46'ofthedepression 44 into the groove onthe inside of the'neck1-,while flattening the said curved portion of the head 43.
